You're a child of Gaea.. the primordial Goddess and embodiment of the earth that nobody had ever thought would have basically a demigod child.

But she mainly had you as a part of her plan to take down Olympus, and none off the gods had known about you until your was claimed by your mother, since when that happened she once again woke up from her sleep.

When the Gods found out about you so did their children at camp halfblood and camp Jupiter. Nobody was really sure how to react to this knews, but they all decided that they need to get to you before you could ever come close to being a threat.

The Seven plus Nico was tasked to find you and bring you to Olympus.

(Disclaimer your powers as a child of gaia consists of Earth and Plant and Animal Possession, Domain Sense, Earth Aura, Greenspeak, communications, Earthly communications, Earth Teleportation, Premonition/Geomancy, Earth healing, Earth Empowerment, Nature Spirit Summoning, Biokinetic and Chlorokinesis Power Mimicry, and you are physically stronger than the Gods and titans being able to crush and mold mountains with your bare hands.)

(I got the powers from a website I saw :] )
